The invention provides a method of operating a batch mixer for producing first and second numbers of mixtures from first and second numbers of batches of materials to be mixed in the batch mixer, the batch mixer comprising a mixing chamber, a mixing element disposed within the mixing chamber, the mixing element and the mixing chamber being configured for providing an identical flow of the materials to be mixed within the mixing chamber and around the mixing element regardless of in which of the first and second opposite directions the mixing element is rotated, and a motor assembly coupled to the mixing element for rotating the mixing element for mixing the first and second numbers of batches of materials to be mixed for producing the first and second numbers of mixtures. The method comprises the steps of energizing said motor assembly for rotating said mixing element in said first direction, for each one of the first number of batches of the materials to be mixed: loading the one of the first number of batches of materials to be mixed into the mixing chamber, mixing the one of the first number of batches of materials for producing one of the first number of mixtures, and removing the one of the first number of mixtures from the mixing chamber, energizing the motor assembly for rotating the mixing element in the second direction, and for each one of the second number of batches of the materials to be mixed loading the one of the second number of batches of materials to be mixed into the mixing chamber, mixing the one of the second number of batches of materials for producing one of the second number of mixtures, and removing the one of the second number of mixtures from the mixing chamber.

The invention pertains to a pellet millfor forming pelleted material, the pellet millcomprising: A diehaving a cylindrical inner surfacewith a plurality of aperturesformed therein and extending to the outside of the die, the volume bounded by said inner cylindrical surfacedefining a die chamber. At least two cylindrical rollersadapted to travel over said inner cylindrical surfaceof the diein a rolling motion. Drive means for causing relative rotation of the dieand the rollers, so that the rollerswill travel over the inner cylindrical surfaceof the die, thereby forming wedge-shaped spacesbetween the rollersand the inner cylindrical surfaceof the die. A feed system, comprising at least two conduits, one associated with each of the at least two rollers, extending into the die chamber, each of the conduitshaving a side openingfor feeding the pelletizable materialinto the wedge-shaped spacesbetween the rollersand the inner cylindrical surfaceof the die, the side openingextending axially along the conduitand having an extension that is equal to the length of the rollers, wherein at least one of the conduitsis configured for feeding the pelletizable materialdirectly to a wedge-shaped space, which is at a higher location in the die chamber than said conduit

Mixer housing

The present invention provides a pellet mill () for preparing pellets from a pelletizable material supplied to the pellet mill (), comprising a frame (), a main axle () rotatably mounted in said frame () and having a first end () and an opposite second end (), an annular die () being supported by said second end () and having an inner surface () for receiving a portion of said pelletizable material () supplied to said pellet mill (), an outer surface (), and a plurality of radial channels () extending from said inner surface () to said outer surface () for preparing pellets from said portion of said pelletizable material (), a roller holder () supported by said frame (), a number of roller axles (), each of said number of roller axles being moveably mounted in said roller holder (), said roller axles may move in said roller holder () in the event of an overload to prevent damage to the pellet mill, a number of rollers (), each of said number of rollers being rotatable around a corresponding one of said number of roller axles (), each of said number of rollers () being adapted to press said portion of pelletizable material () against said inner surface () for rolling, in response to rotation of said annular die (), along said inner surface () of said annular die () for forcing said portion of said pelletizable material () from said inner surface () to said outer surface () through at least one of said plurality of radial channels () for preparing said pellets, and a number of actuators (), each of said number of actuators () being operatively connected to a corresponding one of said number of roller axles () and being adapted to prevent movement of said corresponding one of said number of roller axles () relative to said die holder () for maintaining a distance between a corresponding one of said number of rollers () and said inner surface () of said annular die ().

Pellet mill having improved construction

In a roller adjustment apparatus for an extrusion mill, comprising a cylindrical die () with radially extending extrusion channels and a number of rollers () within the die, rotatable about their axes and co-operating with the die to press material to be treated through the extrusion channels in the die wall, the adjustment apparatus comprises eccentrically journalled bearing shafts () for mounting the rollers (), said eccentrically journalling of the shafts () providing a radial adjustment of the position of the rollers () relative to the die (), the rotation of the eccentrically journalled shafts () is provided by means of extension arms () fixedly mounted on the ends of the eccentrically journalled shafts (), and said extension arms () being connected to an axially movable connection element () by means of articulated connected linkage rods (), and said connection element () being connected to a rod () provided with its axis in the axis of the die () and extending to a position outside the material flow of the extrusion mill to move the connection element () in the direction of the axis of the die (), said axial movement being provided manually or by means of a suitable actuator connected to the rod (). In this way, only simple mechanical components, such as linkage rods () and connection elements () are positioned close to the rollers and these components are moved by manual adjustment or by means of suitable actuators positioned outside the aggressive environment close to the rollers of the extrusion mill.
